# --description--

The same syntax can be used to change the value of an existing key.

Just before the `print()` call, access the `species` key and reassign its value to `Cavia porcellus`.

# --hints--

You should reassign the `copper['species']` to the string `Cavia porcellus` before the `print()` call.

```js
({ test: () => assert.match(code, /^copper\s*\[\s*("|')species\1\s*\]\s*=\s*("|')Cavia porcellus\2.*^print\s*\(\s*copper\s*\)/ms) })
```

# --seed--

## --seed-contents--

```py
--fcc-editable-region--
copper = {
    'species': 'guinea pig',
    'age': 2
}
copper['food'] = 'hay'

print(copper)
--fcc-editable-region--
```
